Mostly, much more advanced sail technology. It's the sort of thing that might start being interesting with third- or fourth-generation sails. We need a lot more experience before we get that ambitious. We also probably need an assembly facility in high orbit: advanced sails are mostly semi-rigid -- you can't have them unfold from a little package, so they'd have to be built in space -- and low orbit has too much air drag. -- SVR4 resembles a high-speed collision | Henry Spencer @ U of Toronto Zoology between SVR3 and SunOS. - Dick Dunn | henry@zoo.toronto.edu utzoo!henry ------------------------------ Date: Tue, 4 May 1993 17:53:41 GMT From: Henry Spencer Subject: Communication satellite station Newsgroups: sci.space In article <1993May3.214634.24899@noao.edu> elowitz@noao.edu (Mark Elowitz) writes: >Does anyone know if NASA has explored the possibility of placing >a communication relay satellite stations in highly elliptical >orbits in the Jovian and Saturnian systems... A reasonable idea if you've got customers for them. (Something like this was briefly considered as a workaround for Galileo's antenna problem.) It really only makes sense if you've got multiple missions to the same planet underway at the same time -- your relays won't last forever -- and current NASA plans have exactly one mission to each of those planets (Galileo and Cassini, respectively). >Also, has anyone explored the possibility of transmitting >telemetry back to earth via laser or are the power constraints >too large. Yes, it's been explored. The big constraint is not power, but the need for very accurate pointing because of the very narrow beams. It's being pursued and will probably be used eventually; it has a lot of promise but the technology for it is not ready for operational use yet. -- SVR4 resembles a high-speed collision | Henry Spencer @ U of Toronto Zoology between SVR3 and SunOS. - Dick Dunn | henry@zoo.toronto.edu utzoo!henry ------------------------------ Date: Tue, 4 May 1993 18:45:10 GMT From: Dillon Pyron Subject: Drug-free satellites Newsgroups: sci.space Come on, isn't this going just a little too far.

I know gyros are generally used for >reference frames, but how would a big gyro and a small momentum wheel >differ. The terminology in this area is a complete mess, so don't expect people to agree on what the words mean. That being said... A gyro is a sensor, a small wheel rotating in *extremely* expensive bearings which absolutely minimize perturbing forces that might precess its axis of rotation. A reaction wheel is a wheel that is nominally stationary, but is spun up to a modest speed in one direction when you want the satellite to rotate in the opposite direction. The wheel needs to have substantial mass; the bearings don't have to be anything terribly special. A momentum wheel is a reaction wheel whose nominal state is spinning at a particular speed. The point of doing this is that a small torque will disturb a satellite's attitude much less if it has to fight the gyroscopic effects of a spinning wheel first. Again, bearings are not that important (because you just use an electric motor to compensate for any loss of speed), but the stabilizing effect requires considerable mass. The ultimate form of this is the spin-stabilized spacecraft, where the whole thing spins. A control moment gyro (poor term) is a momentum wheel operated at constant speed, with attitude control done using precession forces rather than speed variations. See "Spacecraft Attitude Determination and Control", James Wertz ed., for lots more detail. I believe a detailed reference is in the FAQ. -- SVR4 resembles a high-speed collision | Henry Spencer @ U of Toronto Zoology between SVR3 and SunOS. - Dick Dunn | henry@zoo.toronto.edu utzoo!henry ------------------------------ Date: 4 May 1993 22:02 UT From: Ron Baalke Subject: JPL Mission Updates - 04/27/93 Newsgroups: sci.space,sci.astro,alt.sci.planetary PLANETARY MISSION STATUS April 27, 1993 VOYAGER 1 and 2: The two Voyager spacecraft continue their interstellar mission with fields-and-particles data acquisition. Voyager 1, launched September 5, 1977, is currently 7.8 billion kilometers (4.8 billion miles) from the Sun, receding at 17.6 km per second, after flying by Jupiter and Saturn in 1979 and 1980; Voyager 2, launched August 20, 1977, to fly by Jupiter (1979), Saturn (1981), Uranus (1986), and Neptune (1989), is now 5.97 billion kilometers (3.7 billion miles) from the Sun. Contact: Mary Hardin, (818) 354-5011. MAGELLAN: The Magellan spacecraft is continuing its survey of the gravitational field of Venus, utilizing precise navigation of the spacecraft in the near-Venus portion of its elliptical orbit, through May 15, 1993. The Project plans to begin maneuvers to circularize the orbit on May 25. Magellan was launched May 4, 1989, aboard Space Shuttle Atlantis with an IUS injection stage; it radar-mapped more than 98% of Venus's surface from September 1990 to September 1992. Contact: Jim Doyle, (818) 354-5011. GALILEO: The spacecraft is now en route to Jupiter, scheduled to go into orbit there on December 7, 1995. Spacecraft performance and condition are excellent except that the high-gain antenna is only partly deployed; science and engineering data are being transmitted via the low-gain antenna. The Project is now planning to use the low-gain antenna for the Jupiter mission and the August 1993 encounter with asteroid Ida. Galileo was launched October 18, 1989, by Space Shuttle Atlantis and an IUS, and flew by Venus in 1990 and Earth in 1990 and 1992 for earlier gravity assists and asteroid Gaspra in October 1991 for scientific observation. Contact: Jim Wilson, (818) 354-5011. ULYSSES: The spacecraft is in a highly inclined solar orbit, now almost 30 degrees south (relative to the Sun's equator), in transit from its Jupiter gravity assist in February 1992 toward its solar polar passages (about 80 degrees south and north) in 1994 and 1995. Ulysses spacecraft condition and performance are excellent, and cruise science data-gathering continues. The Ulysses spacecraft was built by the European Space Agency and launched October 6, 1990 aboard Space Shuttle Discovery, with IUS and PAM-S stages. Contact: Diane Ainsworth, (818) 354-5011. TOPEX/Poseidon: The satellite is healthy, and all scientific instruments are performing normally, typically providing three playbacks per day. The mission is to map ocean circulation. TOPEX/Poseidon was launched August 10, 1992, aboard Ariane 52. Contact: Mary Hardin, (818) 354-5011. MARS OBSERVER: Spacecraft health and performance are normal, and Mars Observer is on its planned trajectory leading to Mars orbit insertion August 24, 1993, with the mapping orbit attained November 8 and science operations planned to start November 22. The Joint Gravitational Wave Experiment, in which Mars Observer was joined by Ulysses and Galileo, completed data-gathering April 12, and data analysis has begun. Mars Observer was launched aboard a Titan III/TOS vehicle on September 25, 1992.

I'm not a history major either, but my point was that you are making a *major* mistake if you assume that native American culture in North America was that found in 1800. You're thinking "tribal hunter-gatherer", when you should be thinking "the Aztecs' country cousins". Eastern North America before Columbus was -- as best we can tell, since few explorers penetrated the area early enough to report on it -- made up of substantial city-states based on large-scale agriculture, with organized government and religion. At the time of the American Revolution, the biggest city in the Colonies -- Philadelphia -- had a population somewhat less than what the native city of Cahokia (in the Great Lakes region) had several centuries earlier. The idea that the natives were simple primitives living happily in harmony with nature for millennia before the Europeans arrived is simply a myth. The native cultures in eastern North America in 1800 were the starveling remnants of a crashed civilization, and a recently-crashed one at that. They were hunter-gatherers; their not-distant ancestors had been farmers, city dwellers, and priests. The idea that Europeans "corrupted" these people by introducing notions like agriculture and religion is silly. (Mind you, if you want to blame the Europeans for something, you don't have to go farther than asking "just exactly why did their civilization crash?". Nobody knows for sure, because there's so little data, but it seems likely that smallpox and other European diseases were largely responsible. Even the De Soto expedition, not long after Columbus, found city-states that had been seriously hurt by outbreaks of new diseases. And even measles or chicken pox can be devastating to a population that has never been exposed.) >intent was not to discuss native american history, but rather to ask... >if we encounter life elsewhere, will we FORCE our culture on them as we >have done in the past, or will we tolerate their way of life and maybe >even try to learn from it? Good point, but it can be taken further. Suppose the first Europeans beyond the Appalachians had had the best of intentions (they didn't) and had known (they didn't) of the crash of the previous civilization in that area. Should they have tried to *help* the natives? Bear in mind that in many areas, the North American natives wholeheartedly cooperated in their own assimilation. Being able to trade a few beaver pelts for a metal knife or axehead was a *good deal* to a stone-age culture, the sort of trade that could make the difference between hungry misery and happy prosperity. The introduction of the horse drastically transformed native life in the Southwest. I've got a wool blanket in a traditional Hudson's Bay Company design, complete with markings indicating the price in beaver pelts -- such blankets were a sought-after item among the Canadian natives once. Of course, all of this was the thin edge of the wedge in one sense... but was it *wrong*? The answer isn't obvious. Cultures do change, even if you leave them alone. This sort of dilemma is much more likely to occur, and much harder to resolve, than drastic dichotomies like "should we rape and pillage, or do a PhD thesis about them?". -- SVR4 resembles a high-speed collision | Henry Spencer @ U of Toronto Zoology between SVR3 and SunOS. - Dick Dunn | henry@zoo.toronto.edu utzoo!henry ------------------------------ Date: 4 May 1993 20:06:42 GMT From: steve hix Subject: Philosophy Quest.

It's not even that easy: Unless, when we come across an alien culture, we remain invisible to them, the fact that they know we're there is probably going to have an immense effect on them. An alien culture stumbling over us will also have an immense impact on us, one that might even destroy our culture, intentionally or not.
